The C7 had multi stage DSC (known as PTM) as well. Ultimately all manufactures are using the same electronics/sensors developed by Bosch etc., only the calibration is different. BMW are not at the cutting edge here by any stretch, this is probably the first BMW implementation of DSC that is actually usable in a track setting without being overly intrusive.

Explained by BMW in the Q&A to the video.
MDM and variable TC operates in different ways, where MDM applies DSC (incl brake activation) to straighten the car. In variable traction control you have no brake operation to straighten the car, it's just traction control to control the slip (basically a drift aid 😉. |

I'd say it is the other way around. MDM use the front brake quite significantly to manage the car's attitude on track putting an even greater burden on the front tires. The new TC system should put significantly less burden of the front tires.

As for the G80/82 traction control I was mostly referring to the rears hehe

Is MDM a standard thing even on the 6 mt or do I need to tick the M drive professional to get it? I'm not particularly interested in the 10 stage traction control, it seems to be mostly a drifting aid... I do like having the back play a little but I would never drift a car on public roads. Not taking it to the track either. Also I assume that for people who truly know how to drift they wouldn't actually need the 10 stage TC to do it. Correct?

The M Traction Control only manages traction (rear wheel slip), not stability like DSC or MDM (understeer/oversteer), it works like early Lotus traction controls or motorcycle traction controls by reducing power through ignition timing or throttle closure, not with the brakes. DSC and MDM beyond a certain degree of yaw (lower with DSC, higher with MDM) brake the front wheels to prevent you from spinning, with MTC this does not happen, it only reduces the rear wheel power based on the level selected from 1 to 10. |

How interventionist is the MDM? Is it variable for example if you're still in control through the steering wheel, does it allow you to straighten the car on your own or does it intervene every time according to preset parameters?

Yes you can steer back the car but only if you don't get to close to the MDM threshold limit, once you hit that it tries to straighten you back by applying the brakes in a very effective manner. At least that's my experience with my M2 with GTS MDM coded in.
